Well, starting with the obvious are the fork tubes level at the top clamp in the triple tree? It also looks to me that the bottom clamp on the left looking at the photo is a bit lower than the right. Notice that the yellow paint on the bolt head is missing on that side also.
Damaged in shipping, maybe but you would think there would be some other sign of damage.
Seller lying to the buyer, it happens. There is some reason the bike has such low miles. Was it parked for many years after it took a hit to the front end?
Like retro says losen things up, get the fender off and see where you are at. Looks like a nice find and will be well worth the effort to get it straightened out.
